ADJUSTABLE INKING MECHANISM.

Application filed September S, 1921. Serial No. 499,157.

To @ZZ- ywhom t may (foncer/a:

Be it known that I, CLAUDE L, Posr, a citizen of the United States, residing at Chicago, in the county of Cook. and State of illinois, have invented certain new and useful improvements in Adjustable linking Mechanisms, of which the followingv isa description.

My invention relates to inking mechanisins7 and more-particularly to an inlring roll havingan ink receiving reservoir therein which may be conveniently filled, and being provided 'with adjustable means whereby the inl( in said reservoir may be fed in any desired amounts to the inlring surface of the inling roll intermittently.

Another object of my invention is to provide means for reciprocatingthe inling roll while it is being rotated so that the ink is more evenly distributed on the. cooperating inking rolls or distributing rolls over their entire surfaces.

Another object of my invention is to provide a device ofl the character described which may be easily assembled or disassembled for inspection or the like, and whichlis extremely simple, durable, compact, efficient and satisfactory for use wherever found applicable. y

lil/[any other objects and advantages of the construction herein shown and described will be obvious to those `skilled in lthe art from the disclosure herein given.

To this' end my invention consists in the novel construction, arrangement and combination of parts herein shown and described,

and more particularly pointed out in the claims.

ln the drawings, wherein characters indicate like or parts,

Fig. 1 is a top view of my ing roll held in position frame;

Fig. 2 is an enlarged sectional view taken Fig. 7 is an end elevation of a portion of the printing frame with my device 1n place vgearing'. arm 12 comprisesa worm gear 14 at the end. ofthe drive shaft 15 ofthe roll, said wormv in Athe printingI Fig. 8 is a front elevation of the saine with portions broken away; Fig. 9 is a sectional view taken substantially on theline 9 9 of Fig. 7;

Fig. 10 is a sectional view taken substantially' on the line 10 10 of Fig. 7i;

Fig. 11 is a sectional view taken substantially on the line'11 11 of Fig. 10; and` Fig. 12 is a sectional view taken substantially on tlie'line 1.2 12 of Fig. 8. l

Reerring to the drawings, where lI -hav illustrated thevpiieferred embodiment of my' invention, 1 indicates the side frames of a. printing mechanism of any suitable or desired construction, said frame having upwardly extending pairs of arms 2- 2y at itsopposite sides, and there being, slot 3" between each of said pair of arms. Rolls il, 5, (i and 7 are suitably held in place or carried by said frame, tlie'1olls.11.aiid 5 being adjustablv gournaled therein in jour-,- nal bones55, as shown in Figs, 1 andV 2. The

rolls l and 5 are suitably geared togetherk or driven byV any' suitable means, not shown. The shaft 9 of the roll 6 is. annularly slotted at 1() yso vas to receive the yoltedend-` 11. 11 of a reciprocating arm 12said arm.

being'pivoted at its end and adaptedto be oscillated on saidpivot through suitable The gearing for oscillating the meshing with a gear wheel 16, carried by an arm 1i' secured'to theframe in any. suit.- able manner. A pin 18 projects from the face of the'gear wheel 16, andv is adapted.

to slide in adongitudinal slot `19 provided in the arm 12, .said pin. 18 being eccentric to the pivotal airis of the gearwheel 16. .It

is obviousthat as the shaft -15 rotatesthe -v worm 14 will rotate the gear wheelk 1 6 andv ,y

the eccentrically mounted pin 18 will slide vin the slot 19l tooscillate the arm 12 on the pivot, this movement being transmitted to reciprocate the roll 6.

The inlting roll 7 is in frictional contact with the roll 6, as shown in Figs. 1 andl 2, the shaft 20 supporting said roll at its ends. A bearing sleeve 21p surrounds tlieshaft 20,

said bearing sleeve being cut away or recessed between its lends, as at 22, on opposite sides so as to non-rotatably it between the opposed pair of frame arms 2, asshown in the drawings. In order'to prevent longitudinal or axial movement of the sleeve relatively to the frame, a collar 23 is positioned about the sleeve and adjustably secured thereto by a set screw 2li, or any other suitable or equivalent means for the purpose,l

the collar 23 being recessed on opposite Sides, as at 25, and providing shoulders 26 overlying the opposite sides of the trame arms 2, thus preventing relative lateral movement therebet-ween, but permitting the sleeve, with its attached collar, to be slid into place downwardly between the spaced arms 2, as shown in F ig. l. |The collar 23 is of a lesser length than the length between the shoulders or ends of the recesses 22 so that the sleeve inay be adjusted relative thereto.

The inking roll 7 has an inl; well or inki'eceiving chamber 27 therein, said chamber being formed by slotting the roll longitudinally thereof, said slot opening on the periphery of the roll. Within the chamber 27 is reif'olubly mounted a roller 28, supported by a shaft 29 at its ends, the periphery of the roller being substantiallytlush with the peripheral surface otv the roll 7, as shown in 9. it one end of the sha-ft 29 is mounted a gear or ratchet wheel 30, said gear being` adapted to be intermittently engaged by a preferablyv resilient or yieldable tooth member 3l carried by the sleeve 2l. As the roll 7 is in trictional contact with the roll 6, it is driven and reciprocated vthereby, and the teeth of the gear 30 which is eccentrically mounted relative to the rotational aXis ot the roll 7 will be intermittently engaged by the laterally oti'set or projecting tooth end 32 ot' the resilient member 3l as shown in Figs. 2 and 6, whereupon the roller 28 will be partially rotated relative to the rotation ot' the roll 7 so as to carry the inl; to theperiphery of the roll 7, where it may be distributed to the roll G and to the type roll, as desired.

The ink reservoir may be closed by any suitable means, and removably held in place. Inthe embodiment shown, the cover 33, having downturned or laterally offset ends 34, is pivotally mounted on the roll 7 by screws 35 through said ends, or any other equivalent ineans for the purpose, said cover being arcuate or curved in cross section to conform to the peripheral surface ot the roll 7, and overlying one edge of the slotted chainber 27. rIhe screws may be tightened to hold the cover iirmly in place, or any other suitable or preferred latching means, such as a spring-pressed detent, may be used.

.Vhenever it is desired to lill the chamber or to open it for inspection, or for any other desired purpose, the cover is drawn back, as shown by the dotted lines in Fig. 9, whereupon easy `access is had lto the chamber 27 and to the parts therein.

It is well known that printing inks vary in their consistency or in body, and therefore I have provided means for regulating' the flow ot the' ink from the reservoir to the 4periphery ot the printing roll to compensate tor this variation in the body ot the inks. The end walls oi the roll 7 are bored and screw-threaded as at 36 (see Fig. 4f), and into these threaded apertures are adjustably positioned busliiiigs37, said bushings having screw-threads 38 on their exterior, cooperating with the threads 36, and also being provided with a head 39 preferably of square, hexagonal or other suitable non-circular peripheral outline, so that it may be readily turned by hand or by any suitable tool. The bushings 37 are eccentrically bored at 40, to torni bearings for the axle 29 of the roller 28.

rThus it will be seen that if the bushings 37 are partially rotated, the roller 28 will be adjusted radially of the printing roll to control the size o'f the opening leading to the periphery.

Having thus described my invention, it is obviousy that various immaterial modifica-- tions inay be made in the same without departing from the spirit of my invention; hence l do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described, or uses inentioned.

, liVliat I claim as new and desire to secure by Letters Patent is:

1. An ink roll having an ink reservoir therein openingonto the periphery, a roller extending longitudinally in said opening to control the iiow of ink therethrough, and.

bushings removably carried by said roll at opposite ends and each having an eccentric bore therethrough to provide bearings lor said roller, whereby said bushings may be independently adjusted to move said roller radially to regulate the passage of inl; through said peripheral opening.

2. An ink roll having an ink reservoir therein openingvonto the peripheri a roller in said opening to control the flow of ink therethrough, and eccentrically bored bushn ings in said roll at opposite ends to form bearings for said roller, whereby said bushings may be adjusted to move Said roller radially to regulate the passage oi inl.: through said peripheral opening.

In testimony whereof, I have hereunto signed my name in the presence ot two subscribing witnesses. Y
